Every now and again I have a message which comes up saying Windows accelorator driver stopped working for Windows XP and has recovered. I have Windows 7 home premium so why would this message keep appearing every so often.
Is there any text before "windows acc...." in the error message? From the information supplied I would guess you are running W7 32bit and you've either upgraded from XP or you have loaded an XP grahics driver - I've only seen that sort of message from video drivers. I would check that either an updated Toshiba driver or a "WHQL" certified laptop driver is available from the graphics chipset's web site.
I think you mean the error: Display driver Intel Graphics Accelerator Drivers for Windows XP stopped responding and has successfully recovered
This means that your graphic card driver stopped working properly.
You should update this driver… I assume its Intel GPU due to the error message…so the latest driver can be downloaded from Intel page as well from Toshiba European driver page.
